Description

Full-automatic high-speed drill unloading device

Technical Field

The invention belongs to the technical field of water drill production, and particularly relates to a full-automatic high-speed drill unloading device.

Background

The rhinestone is a very important accessory of ornaments and clothes, and the traditional polishing roller for the rhinestone is a cylindrical polishing wheel in an integral form for polishing the surface of the rhinestone.

The patent publication No. CN100484711 discloses a method for polishing and grinding the end face of a rhinestone, which comprises arranging rhinestones and then forming a plastic-suction sheet (a circular disc, on which a large number of adsorption holes are uniformly distributed, and the rhinestones are bonded to the adsorption holes through rosin and the like) by plastic suction to polish and grind the end face of the whole disc (or integrally spraying paint through the plastic-suction sheet), and removing the rhinestones from the plastic-suction sheet after the processing is completed.

In the prior art, a rhinestone is usually separated from a plastic sheet through an automatic unloading device, for example, a patent with the application number of 200920192598.3 discloses an automatic unloading machine, for example, a patent with the application number of CN 201610981852.2 discloses an unloading machine, for example, a patent with the application number of 201620254706.5 discloses an unloading device after silver spraying on the rhinestone, for example, a patent with the application number of 201710355572.5 discloses a novel unloading machine, and for example, a patent with the application number of 201811617602.6 discloses an automatic unloading machine.

The devices all need to adopt a manipulator (structure such as a sucker and the like) to convey the blister sheet to the feeding end of the drill unloading device.

The applicant found that when using a robot for transfer: the rhinestones are very small, so that the processing amount is very large, a large amount of plastic suction sheets need to be processed every day, and the plastic suction sheets are not well stacked and are not well conveyed to the initial suction position of the manipulator. In addition, in the prior art, a rotating brush is usually adopted to brush off rhinestones on the plastic sheet, the drill unloading rate is between 90 and 95 percent, and the plastic sheet is usually cleaned manually; while the brushes also need to be cleaned or replaced periodically.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 9, an embodiment of the present invention provides a full-automatic high-speed drill unloading device, which includes a tunnel oven 21 (tunnel structure, in which baking structures are disposed on both upper and lower sides of an oven conveyor belt 20) disposed in a front-back direction, an oven conveyor belt 20 passing through the tunnel oven 21 in the front-back direction, an automatic drill brushing structure (for separating a drill from a plastic-absorbing sheet (usually circular)) on a rear side of the oven conveyor belt 20, and an automatic feeding structure (for automatically feeding a sheet) in front of the oven conveyor belt 20. Wherein, automatic feeding structure includes the vacuum pump, feed frame 10 upper portion and can be around to reciprocating motion's horizontal sliding plate 11 (feed frame 10 is equipped with the gliding slide rail in the front and back along the anteroposterior for horizontal sliding plate 11, by corresponding structure (like synchronous belt drive structure) drive) and horizontal sliding plate 11 on manipulator 12 etc, be equipped with on manipulator 12 with 13 big or small complex sucking discs 14 of plastic uptake piece, sucking discs 14 pass through pipeline and vacuum pump connection, it is the disc that just level set up with plastic uptake piece 13 size is more or less (preferred slightly bigger). The structure is basically the same as that of the existing drill unloading device, and the difference is that:

the automatic feeding structure in this embodiment further includes a blister sheet storage rack (for storing blister sheets 13 and delivering them to the right below the manipulator 12) in front of the oven conveyor belt 20 and capable of rotating in an indexing manner, and a blister sheet lifting structure (for ensuring that the manipulator 12 sucks the blister sheets 13) on the feeding rack 10 and moving up and down. The blister sheet storage rack comprises a base 15 (the feeding rack 10 is arranged on or not arranged on the base 15), a turntable 16 (horizontally arranged plate-shaped structure) arranged on the base 15 and rotated through a vertical rotating shaft, an indexing motor arranged on the base 15 and used for driving the turntable 16 to index and rotate, a plurality of blister sheet stacking areas 17 (specifically, a circular area which is slightly larger than blister sheets and is uniformly distributed around the rotating shaft on the turntable 16 and corresponds to an indexing angle, the plurality of blister sheet stacking areas 17 are positioned on the same circle concentric with the rotating shaft, and included angles between every two adjacent blister sheet stacking areas 17 are equal and equal to the indexing angle), and the like. Wherein, the turntable 16 is horizontally arranged and can rotate (driven by an indexing motor) around the rotating shaft in an indexing way, and a tray 18 (specifically, a horizontal round plate, the upper surface of which is smooth and can move up and down) which is matched with the size of the plastic sheet 13 (equal to, slightly larger than or slightly smaller than the plastic sheet, preferably slightly larger (but the diameter is smaller than the diameter of the circle enclosed by the guide rod 19)) and is circular is arranged on the plastic sheet stacking area 17. A plurality of guide rods 19 are uniformly distributed on the plastic sheet stacking area 17 around the tray 18 and the plastic sheets 13 so as to prevent the stacked plastic sheets from being inclined or falling off during lifting. The guide rods 19 are arranged in the vertical direction and have a height which is designed according to the suction position of the manipulator and are embodied as round tubes. The plastic-absorbing sheets 13 (with the diamond surfaces on the lower side) are stacked on the tray 18 and located in a stacking area surrounded by the guide rods 19.

Wherein, the supporting plate 110 is positioned right below the blister sheet stacking area 17 to be fed and is positioned between the base 15 and the turntable 16. The outside of each plastic sheet stacking area 17 is provided with a notch 111 (slightly larger than the supporting plate 110) for the supporting plate 110 to pass through upwards. The pallet 110 is passed upwardly through the notch 111 to lift the tray 18 upwardly. The stepping motor is of a common structure, can upwards step by one height after sucking 1 plastic suction piece each time, and can also upwards step by one height (incapable of influencing the sucking of the manipulator 12) after sucking a plurality of plastic suction pieces, and the stepping height is designed according to the thickness of the plastic suction pieces, the number of the suction pieces, the stepping and the like. The width of the supporting plate 110 is required to stably lift the tray 18, for example, the width is greater than 5cm and smaller than the distance between the 2 outer guide rods 19.

The working process is as follows: each time the turntable 16 rotates an index angle (e.g., 90 °), it rotates a blister sheet stacking area 17 directly above the carrier plate 110. The supporting plate 110 passes through the notch 111 upward and ascends further to make the plastic sheet 13 at the top layer be located at the top of the guide rod 19 and always located at the same height, and the manipulator 12 sucks the plastic sheet 13 at the top layer for feeding (other plastic sheet stacking areas 17 can add plastic sheets manually or automatically). When all the blister sheets 13 on the tray 18 are taken out (not all the blister sheets are taken out), the pallet 110 moves downward again to be directly below the blister sheet stacking area 17, the turntable 16 rotates by an index angle again to perform feeding of the adjacent blister sheet stacking area 17, and so on, thereby realizing continuous feeding of the automatic feeding structure.
